  1. aRA, rheumatoid arthritis; IL, interleukin; LIF, leukemia-inhibitory factor; COMP, cartilage oligomeric protein; OP-1, osteogenic protein 1. Spearman's rank correlation coefficients (IL-1, IL-6, IL-8, IL-11, LIF, osteocalcin, COMP and OP-1) for the RA cohort are expressed as Spearman's ρ and P values. A total of 22 RA patients were sampled, five male and seventeen female.
